To calculate the Heat Index (HI):
\[ HI = 0.5 \times \left[ T + 61.0 + \left( (T - 68.0) \times 0.12 \right) + (RH \times 0.094) \right] \]
Where:
The Heat Index is a measure that combines air temperature and relative humidity to determine how hot it feels to the human body. It is important because it helps us understand the potential risk of heat-related illnesses such as heat stroke and heat exhaustion. By considering both temperature and humidity, the Heat Index provides a more accurate representation of the actual discomfort caused by heat. This information is crucial for individuals who work or engage in outdoor activities, as it helps them take appropriate precautions to prevent heat-related health problems.
Let's assume the following values:
Using the formula:
\[ HI = 0.5 \times \left[ 90 + 61.0 + \left( (90 - 68.0) \times 0.12 \right) + (70 \times 0.094) \right] \]
Calculating the intermediate steps:
\[ HI = 0.5 \times \left[ 90 + 61.0 + 2.64 + 6.58 \right] = 0.5 \times 160.22 = 80.11 \]
The Heat Index is 80.11°F.
Let's assume the following values:
Using the formula:
\[ HI = 0.5 \times \left[ 85 + 61.0 + \left( (85 - 68.0) \times 0.12 \right) + (60 \times 0.094) \right] \]
Calculating the intermediate steps:
\[ HI = 0.5 \times \left[ 85 + 61.0 + 2.04 + 5.64 \right] = 0.5 \times 153.68 = 76.84 \]
The Heat Index is 76.84°F.
